Description
本発明は、コンクリート製の樋門構造物の下部と樋門構造物の直下の遮水矢板壁とを継ぐ、遮水性可撓性の樋門構造物下部構造に関する。 The present invention relates to a water-insulating flexible lock gate structure lower structure that connects a lower portion of a concrete lock gate structure and a water shielding sheet pile wall directly under the lock gate structure.
河川堤防には、取水や排水のため、河川堤防を横断する樋門が設置されることがある。従来の樋門は、例えば、図７に示すように、箱状や筒状の樋門本体部１０１およびコンクリート遮水壁部１０２を備える。コンクリート遮水壁部１０２は、樋門本体部１０１の堤内側および堤外側の開口部、並びに中間などの適宜の箇所において、樋門本体部１０１の外周部の左右両側面および上方に張り出すように設けられている。樋門は、樋管と称されることもある。 On river dikes, locks that cross river dikes may be installed for water intake and drainage. For example, as shown in FIG. 7, the conventional lock gate includes a lock-type main body portion 101 and a concrete impermeable wall portion 102 having a box shape or a cylindrical shape. The concrete water-impervious wall portion 102 protrudes to the left and right side surfaces of the outer peripheral portion of the lock main body 101 and to the upper side at appropriate locations such as the opening inside and outside the bank of the lock main body 101 and the middle. Is provided. Xiamen is sometimes referred to as 樋 管.
また、樋門には、複数の鋼矢板１０３で構成される鋼矢板遮水壁１０４が設けられる。鋼矢板遮水壁１０４は、コンクリート遮水壁部１０２の左右両側およびその左右両側の直下、ならびに樋門本体部１０１の直下に配置されている複数の鋼矢板１０３で構成される。鋼矢板遮水壁１０４は、樋門に沿う浸透水流の発生に起因する堤防および樋門の破損を防止し、樋門および堤防周辺の安全性を確保する。 Moreover, the steel gate is provided with a steel sheet pile impermeable wall 104 composed of a plurality of steel sheet piles 103. The steel sheet pile impermeable wall 104 is composed of a plurality of steel sheet piles 103 disposed right and left sides of the concrete impermeable wall portion 102 and directly below the left and right sides thereof, and directly below the lock gate main body portion 101. The steel sheet pile impervious wall 104 prevents breakage of the levee and sluice due to the generation of a seepage water flow along the sluice, and ensures safety around the sluice and levee.
樋門の設置は、例えば以下の様に行われる。まず、図８（図７のＹ１−Ｙ１矢視図である。）に示すように、堤防１０５を点線１０６のように掘削して樋門埋設部を造る。次いでコンクリート遮水壁部１０２が設置される位置の両側およびその直下、ならびに樋門本体部１０１が設置される位置の直下の部分に複数の鋼矢板１０３を打ち込んで鋼矢板遮水壁１０４を形成する。次いで樋門本体部１０１を打設し、最後に樋門本体部１０１および鋼矢板遮水壁１０４を埋め戻す。 Xiamen is installed as follows, for example. First, as shown in FIG. 8 (a view taken in the direction of arrows Y1-Y1 in FIG. 7), the bank 105 is excavated as shown by the dotted line 106 to form a lock burying portion. Next, a steel sheet pile impermeable wall 104 is formed by driving a plurality of steel sheet piles 103 into both sides of and below the position where the concrete impermeable wall 102 is installed, and directly below the position where the lock body main body 101 is installed. To do. Next, the Xiamen body 101 is driven, and finally the Xiamen body 101 and the steel sheet pile impermeable wall 104 are backfilled.
また、河川堤防の周辺地盤は、土圧による圧密沈下が起きることがある。圧密沈下は、水を含んだ地盤の上に構造物を建設した際に、その荷重で土中の水が抜け、体積が減少することによって生じる地盤沈下である。鋼矢板遮水壁１０４は、強固な岩盤に到達するほど深くは打設されない。そのため、圧密沈下が起きると、樋門本体部１０１およびコンクリート遮水壁部１０２の直下に位置する鋼矢板１０３−１には、負の内面摩擦力が作用して、鋼矢板１０３−１が沈下することがある。この場合、樋門本体部１０１およびコンクリート遮水壁部１０２は動かないので、鋼矢板遮水壁１０４の頂面と樋門本体部１０１およびコンクリート遮水壁部１０２の各下面との間に隙間が生じ、この隙間から漏水が起こり、樋門に沿って浸透水流が流れて堤防および樋門の破損をもたらすおそれがある。 Moreover, consolidation settlement due to earth pressure may occur in the ground around the river dike. Consolidation subsidence is the subsidence that occurs when a structure is built on water-containing ground, and the volume of water decreases due to the loss of water in the soil. The steel sheet pile impervious wall 104 is not placed deep enough to reach a solid rock. Therefore, when consolidation settlement occurs, a negative internal frictional force acts on the steel sheet pile 103-1 located immediately below the lock main body 101 and the concrete impermeable wall 102, and the steel sheet pile 103-1 sinks. There are things to do. In this case, since the lock main body 101 and the concrete impermeable wall 102 do not move, there is a gap between the top surface of the steel sheet pile impermeable wall 104 and the lower surfaces of the lock main body 101 and the concrete impermeable wall 102. There is a risk that water leaks from this gap and the osmotic water flow flows along the lock, causing damage to the embankment and lock.
このような問題を解決するため、様々な樋門構造および鋼矢板遮水壁が検討されている。例えば、本出願人は、特許文献１において、矢板壁の沈下と樋管（樋門）自体の沈下の双方に対処して遮水を行うための、樋管、樋管用遮水壁およびこれらを連結する継手を開示している。この樋管用遮水壁は、樋管の両側において樋管の上端部附近から樋管の下端部を越えて下方に延長する樋管側部遮水矢板壁と、樋管底面と所定の間隔をおいて樋管の下方に位置する樋管下遮水矢板壁とを備える。また、この継手は、ゴム・合成樹脂などからなり、樋管の両側において樋管の上端部附近から樋管の下端部を越えて下方に延長する左右１対の垂直部と、該樋管下遮水矢板壁の上端縁と並行に水平方向に延長し該１対の垂直部と相互に連結する水平部を有する伸縮自在の止水部材を備え、該止水部材の各垂直部の外側端部を両側の該樋管側部遮水矢板壁の各内側端部に固定し、該垂直部と該水平部の連結部から上方の各垂直部の内側端部を樋管の各側部に固定し、該連結部から下方の各垂直部の内側端部を該樋管下遮水矢板壁の各外側端部に固定し、該水平部の上側端部を樋管の下端部に固定するとともに、該水平部の下側端部を該樋管下遮水矢板壁の上端部に固定されている。 In order to solve such problems, various lock structures and steel sheet pile impermeable walls have been studied. For example, in the case of Patent Document 1, the applicant of the present invention uses a soot pipe, a soot barrier for a soot pipe, and the like for coping with both the settlement of a sheet pile wall and the soaking of a soot pipe (Xiamen). A coupling to be connected is disclosed. The side wall for the dredging pipe has a predetermined distance from the side wall of the dredging side of the dredging pipe extending from the vicinity of the upper end of the dredging pipe to the lower side of the dredging pipe, and the bottom face of the dredging pipe. And an underwater-impregnated sheet pile wall located below the in-tube. This joint is made of rubber, synthetic resin, etc., and on both sides of the soot pipe, a pair of left and right vertical parts extending downward from the vicinity of the top end of the soot pipe and beyond the bottom end of the soot pipe, A stretchable water stop member having a horizontal portion extending in a horizontal direction in parallel with the upper edge of the water shielding sheet pile wall and interconnected with the pair of vertical portions, and an outer end of each vertical portion of the water stop member Fixed to the inner ends of the side wall of the side wall of the vertical pipe side shielding, and the inner ends of the vertical parts above the connecting part of the vertical part and the horizontal part to the side parts of the vertical pipe. And fix the inner end of each vertical part below the connecting part to each outer end of the underwater shielding sheet pile wall, and fix the upper end of the horizontal part to the lower end of the lower pipe. At the same time, the lower end portion of the horizontal portion is fixed to the upper end portion of the lower-pipe water shielding sheet pile wall.
また、土質によっては鋼矢板の沈下量に比べて樋管の沈下量が大きくなり、樋管の沈下を鋼矢板が妨げ、樋管にクラックが発生することがある。特許文献２には、このようなクラックの発生を防止するとともに、提体内の浸透水による水みちの助長を防止できる樋管が開示されている。この樋管には、鍔状の胸壁・遮水壁が、樋管の外周に管軸方向に所定間隔をあけて形成され、この胸壁・遮水壁と略同一鉛直面内に打設される遮水等を目的とする矢板が可撓性遮水ジョイント（継手）で接続されている。この可撓性遮水ジョイントは、開口部に相当する部分を上方に向けて前記胸壁・遮水壁の底部と両側部とに固定される、外輪郭略コの字状の内プレートと、該内プレートと同一の鉛直面内に存し、開口部に相当する部分を上方に向けて前記矢板に遮水可能に取り付けられる外輪郭略コの字状の外プレートと、該外プレートに外縁部を、前記内プレートに内縁部をそれぞれ遮水可能に取り付けられた外輪郭略コの字状の止水ゴムとを備えている。 Moreover, depending on the soil, the amount of subsidence of the steel pipe becomes larger than the amount of subsidence of the steel sheet pile, and the steel sheet pile impedes the subsidence of the steel pipe, which may cause cracks in the steel pipe. Patent Literature 2 discloses a soot tube that can prevent the occurrence of such cracks and prevent the water from being promoted by the permeated water in the cadaver. In this fistula, a saddle-like chest wall / water-impervious wall is formed on the outer periphery of the fistula at predetermined intervals in the tube axis direction, and is placed in substantially the same vertical plane as the chest wall / water-impervious wall. Sheet piles for the purpose of water shielding and the like are connected by a flexible water shielding joint (joint). The flexible water-impervious joint is fixed to the bottom and both sides of the chest wall / water-impervious wall with the portion corresponding to the opening facing upward, An outer plate that is in the same vertical plane as the inner plate and is attached to the sheet pile so that the portion corresponding to the opening portion can face upward, and the outer edge portion is attached to the outer plate. And an outer contour substantially U-shaped water-stopping rubber attached to the inner plate so as to be water-impervious.
しかしながら、樋門構造物の地盤に対する相対的沈下変位が非常に大きい場合、止水ゴム部材の厚みによっては、止水ゴム部材が完全に折畳まれて樋門構造物と樋門構造物下部の遮水矢板の間に挟まれることで遮水矢板に樋門構造物が乗り上げる形となり、結果として樋門構造物に発生する沈下変位を阻害し、樋門構造物に曲げが生じて、クラックを発生させ、漏水へとつながる恐れもある。また、止水ゴム部材の領域に土砂やコンクリートが侵入してしまうと、止水ゴム部材の撓みを阻害することがある。 However, when the displacement of the lock gate structure relative to the ground is very large, depending on the thickness of the water stop rubber member, the water stop rubber member is completely folded and the lock gate structure and the bottom of the lock gate structure By being sandwiched between the water-impervious sheet piles, the Xiamen structure rides on the water-impervious sheet piles. There is also a risk of causing water leakage. Further, if earth or sand or concrete enters the area of the water-stopping rubber member, the water-stopping rubber member may be prevented from bending.
従って、本発明が解決しようとする課題は、樋門構造物の地盤に対する相対的沈下に対して、確実に変位を吸収し、地盤反力の影響を構造物側へ伝達せず、樋門構造物の破壊や漏水を防ぐことができる、より安全な樋門を提供することにある。 Therefore, the problem to be solved by the present invention is that the displacement of the lock structure is reliably absorbed with respect to the ground, and the influence of the ground reaction force is not transmitted to the structure side. The purpose is to provide a safer lock that can prevent the destruction of objects and water leakage.

The water stop member has a total thickness w all (not shown) bent and folded, and an allowable displacement amount A (see FIG. 2) between the lock structure 201 and the water shielding sheet pile wall 205 under the lock, With respect to the gap distance d between the lower part of the lock structure 201 and the upper part of the impermeable sheet pile wall 205 below the lock gate, the relationship of Expression 1: w all + A <d is satisfied. Here, in the embodiment shown in FIG. 1, the lower part of the lock structure 201 is the lower part of the upper concrete fixing part 206, and the upper part of the water shielding sheet pile wall 205 under the lock is the upper part of the lower concrete fixing part 213. .
また、許容変位量Ａは、樋門に想定される、樋門下の遮水矢板壁２０５の不等沈下や背面土圧等による最大変位であり、環境や法令などにより求められる安全のための数値であり、例えば２００ｍｍである。 The allowable displacement amount A is the maximum displacement expected due to unequal subsidence of the impermeable sheet pile wall 205 under the lock gate or the earth pressure on the back, and is a numerical value for safety required by the environment and laws and regulations. For example, it is 200 mm.
図２は、図１の樋門構造物下部構造において、樋門構造物２０１と樋門下の遮水矢板壁２０５に相対変位が生じた状態を示してあり、その変位が許容変位量と同じ値Ａに達した状態である。樋門構造物下部構造が前記の関係を満たすと、図２に示すように、水平止水部材２０７が完全に折畳まれず、樋門構造物２０１と樋門下の遮水矢板壁２０５（下部コンクリート固定部２１３）の上部に隙間が残るので、遮水矢板に樋門構造物が乗り上げたりせずに、樋門構造物２０１と樋門下の遮水矢板壁２０５の間での荷重の伝達が防げる。そのため、樋門構造物に発生する沈下変位を阻害せず、樋門構造物に曲げが生じないので、クラックの発生による漏水などを防ぐことができる。 FIG. 2 shows a state in which relative displacement has occurred in the lock gate structure 201 and the impermeable sheet pile wall 205 under the lock gate in the lock gate structure lower structure of FIG. 1, and the displacement is the same value as the allowable displacement amount. A is reached. When the Xiamen structure lower structure satisfies the above relationship, as shown in FIG. 2, the horizontal water blocking member 207 is not completely folded, and the Xiamen structure 201 and the impermeable sheet pile wall 205 (the lower part) Since a gap remains in the upper part of the concrete fixing part 213), the transmission of the load between the lock structure 201 and the shield sheet pile wall 205 under the lock gate does not run on the shield sheet pile. I can prevent it. Therefore, the subsidence displacement generated in the Xiamen structure is not hindered, and the Xiamen structure is not bent, so that leakage due to the occurrence of cracks can be prevented.
止水部材は、図１に示すような蛇腹構造であっても平板構造であってもよい。また、止水部材が、図１に示すように厚みｗの板が山数ｎ（図１ではｎ＝２である。）で折られた構造である場合には、前記の式１に加えて、式２：ｗ×ｎ×２＋Ａ＜ｄ の関係を満たす。 The water stop member may have a bellows structure as shown in FIG. 1 or a flat plate structure. In addition, in the case where the water-stopping member has a structure in which a plate having a thickness w is folded at a number of peaks n (n = 2 in FIG. 1) as shown in FIG. , Expression 2: The relationship of w × n × 2 + A <d is satisfied.
水平止水部材２０７は、平板構造であってもよい。平板構造では、平らなゴム板で樋門構造物２０１と樋門下の遮水矢板壁２０５が連結される。水平止水部材２０７（止水部材）が平板構造の場合は、許容伸び率が１００％以内のゴム板で構成される。許容伸び率は、４０％以内であるとより好ましい。 The horizontal water blocking member 207 may have a flat plate structure. In the flat plate structure, the lock structure 201 and the water shielding sheet pile wall 205 under the lock are connected by a flat rubber plate. When the horizontal water stop member 207 (water stop member) has a flat plate structure, it is formed of a rubber plate having an allowable elongation of 100% or less. The allowable elongation is more preferably 40% or less.
クッション部材２０８は、図１の態様では、上部コンクリート固定部２０６と下部コンクリート固定部２１３との隙間に、密着状態で配置され、水平止水部材２０７を囲んでいる。なお、本明細書では、クッション部材２０８が、樋門構造物２０１の下部と樋門下の遮水壁矢板壁２０５の上部との間に密着状態で配置されているという場合には、便宜上本態様のように、クッション部材２０８が、樋門構造物の下部である上部コンクリート固定部２０６と、樋門下の遮水矢板壁２０５を形成する各鋼矢板２０４が埋設される下部コンクリート固定部２１３との隙間に密着状態で配置されている態様も含む。すなわち、他の部材を介して樋門構造物２０１の下部と樋門下の遮水矢板壁２０５の上部との間に密着状態で配置されている態様を含む。 In the aspect of FIG. 1, the cushion member 208 is disposed in close contact with the gap between the upper concrete fixing portion 206 and the lower concrete fixing portion 213 and surrounds the horizontal water blocking member 207. In the present specification, when the cushion member 208 is disposed in close contact between the lower part of the lock gate structure 201 and the upper part of the impermeable wall sheet pile wall 205 under the lock gate, this mode is used for convenience. As described above, the cushion member 208 includes an upper concrete fixing portion 206 which is a lower portion of the lock gate structure, and a lower concrete fixing portion 213 in which each steel sheet pile 204 forming the water shielding sheet pile wall 205 under the lock gate is embedded. The aspect arrange | positioned in the clearance gap is also included. In other words, it includes a mode in which the lower part of the lock structure 201 and the upper part of the water shielding sheet pile wall 205 below the lock gate are arranged in close contact with each other via another member.
このようにクッション部材２０８が密着状態で配置され、かつ水平止水部材２０７を囲んでいることにより、クッション部材２０８は、充填材、並びに土砂及びコンクリートの変形範囲への侵入防止材としての機能を果たす。 Since the cushion member 208 is arranged in close contact and surrounds the horizontal water blocking member 207 in this manner, the cushion member 208 functions as a filler and a material for preventing entry into the deformation range of earth and sand and concrete. Fulfill.
また、クッション部材２０８として、許容応力が、樋門構造物２０１のコンクリート打設時のクッション部材２０８に掛かるグラウト自重圧力より大きいものを用いる。従って、クッション部材２０８は、施工時の仮支えとしての機能も果たす。ここで、グラウト自重圧力とは、グラウトの単位体積重量に打設高さを乗じ求められる圧力であり、一般的には打設高さは１０ｍを超えない。 Further, as the cushion member 208, one having an allowable stress larger than the grout self-weight pressure applied to the cushion member 208 at the time of placing the concrete of the lock structure 201 is used. Therefore, the cushion member 208 also functions as a temporary support during construction. Here, the grout self-weight pressure is a pressure obtained by multiplying the unit volume weight of the grout by the placement height, and generally the placement height does not exceed 10 m.
また、クッション部材２０８として、圧縮応力度が、樋門構造物２０１のコンクリート構造物（上部コンクリート固定部２０６）の許容圧縮応力度未満であるものを用いる。従って、クッション部材２０８は、圧縮変形時に構造物の変位を阻害したり、破壊したりすることを防ぐことができる。 In addition, as the cushion member 208, one having a compressive stress level less than the allowable compressive stress level of the concrete structure (upper concrete fixing portion 206) of the lock structure 201 is used. Therefore, the cushion member 208 can prevent the displacement of the structure from being disturbed or destroyed during the compression deformation.
このようなクッション部材２０８としては、上記の要件を満たす中実品であってもよいが、例えば中空構造が挙げられる。また、材質としては、発泡ゴムが好ましい。図１のクッション部材２０８は、中空構造である。中空構造には、可撓性の止水部材の撓みを阻害しないように、圧縮される際に外側に折れ曲がるように起点を設けることが好ましい。この様な起点としては、クッション部材２０８が中空構造の縦方向の構造体の厚みを少なくとも一部分薄くしたものが挙げられる。例えば、図１に示すような円弧の窪み２１４やくさび状の凹部を設けたもの、縦方向の構造体を２枚の層で構成し、山折り２１５（図２参照）に折らせたい中央部分や付け根部分を１層にして凹部を設けたものが挙げられる。通常、図２に示すように凹部を設けた部分で、反対面側が山折り２１５になるように折らせることができる。このように、水平止水部材２０７の設置領域の両側に１番目に位置するクッション部材２０８の縦方向の構造体がそれぞれ外側に向かって、折れ曲がると好ましい。これにより、止水部材の設置領域に土砂が侵入することによる、クリアランス確保を阻害することを防ぐだけでなく、クッション部材２０８自体が水平止水部材２０７の撓みを阻害することを防ぐことが出来る。中空構造の中空空間には、前記の屈曲を阻害しない範囲で充填物を含むことができる。 Such a cushion member 208 may be a solid product that satisfies the above-described requirements, but may be a hollow structure, for example. The material is preferably foamed rubber. The cushion member 208 in FIG. 1 has a hollow structure. The hollow structure is preferably provided with a starting point that is bent outward when compressed so as not to hinder the bending of the flexible water-stopping member. An example of such a starting point is one in which the cushion member 208 is at least partially reduced in thickness in the longitudinal structure of the hollow structure. For example, an arc-shaped depression 214 or a wedge-shaped depression as shown in FIG. 1, or a central portion in which a vertical structure is composed of two layers and is to be folded into a mountain fold 215 (see FIG. 2). There may be mentioned one in which the root portion is a single layer and a recess is provided. Usually, as shown in FIG. 2, it can be folded so that the opposite surface side becomes a mountain fold 215 at a portion where a recess is provided. As described above, it is preferable that the longitudinal structures of the cushion member 208 positioned first on both sides of the installation area of the horizontal water blocking member 207 bend outward. Accordingly, not only can the clearance be prevented from being inhibited due to the intrusion of earth and sand into the installation area of the water blocking member, but also the cushion member 208 itself can be prevented from inhibiting the bending of the horizontal water blocking member 207. . The hollow space of the hollow structure can contain a filler as long as the bending is not hindered.
図３及び図４は、クッション部材２０８’の折られ方の別の態様である。図３は常態の断面図であり、図４は図３の樋門構造物下部構造において、樋門と鋼矢板の相対変位が許容変位量Ａに達した状態を示す断面図である。この態様では、クッション部材２０８’の縦方向の構造体に設ける凹部を、水平止水部材２０７の設置領域側から外側に２番目以降について内側に設けて、内側に折る態様である。 3 and 4 show another embodiment of how the cushion member 208 'is folded. FIG. 3 is a cross-sectional view of a normal state, and FIG. 4 is a cross-sectional view showing a state in which the relative displacement between the lock gate and the steel sheet pile has reached the allowable displacement amount A in the lower structure of the lock gate structure of FIG. In this aspect, a concave portion provided in the longitudinal structure of the cushion member 208 ′ is provided on the second and subsequent sides from the installation region side of the horizontal water blocking member 207 on the inner side and folded inward.

The inner vertical portion fixing plate 219 includes an upper vertical portion fixing plate 219-1 that is an upper portion from the connecting portion 222 of the vertical water blocking member 218 and the horizontal water stopping member 207, and a lower vertical portion that is a lower portion from the connecting portion 222. It is divided into two parts of a fixed plate 219-2. The outer vertical portion fixing plate 219 ′ is an upper and lower one. The outer vertical fixing plate 219 ′ is connected to the steel sheet pile 204-1 located at the inner end of the impermeable sheet pile wall 203 on the Xiamen side, and the upper vertical fixing plate 219 is the upper vertical plate.

図５の態様では、垂直止水部材２１８が固定された垂直部固定板２１９、２１９’を打設する際に打設を容易にするとともに垂直止水部材２１８が岩石等との接触により損傷することを防止するために下部垂直部固定板２１９−２と外側の垂直部固定板２１９’の下半分を覆う保護板２２４が設けてある。 In the embodiment of FIG. 5, when the vertical portion fixing plates 219 and 219 ′ to which the vertical water blocking member 218 is fixed is driven, the vertical water blocking member 218 is damaged by contact with rocks or the like. In order to prevent this, a protective plate 224 covering the lower half of the lower vertical portion fixing plate 219-2 and the outer vertical portion fixing plate 219 ′ is provided.
